Output skew
1.
Connect an oscilloscope (preferred) or a monitor (acceptable) to the TP output to be
adjusted, via an MTP receiver.
2.
Apply a crosshatch test pattern to one the local (VGA) inputs.
3.
Tie the local input receiving the test pattern signal to the output to be optimized.
4.
Use the test equipment or examine the displayed video image with a critical eye to
determine which video signal — red, green, or blue — is most shifted to the left.
5.
Adjust the leftmost video signal to the right until all three colors are converged.
6.
If either of the two the remaining colors is left shifted, repeat steps 4 and 5.
7.
Repeat steps 2 through 6 for all other outputs.
MTPX Plus Pre-Peak Selection
If the cable between the MTPX Plus and the receiver is longer than 200 feet (61.0 m), turn
the Pre-Peak feature on the MTPX Plus to on. For shorter cables, turn the feature off.
MTP Receiver Level and Peaking Setting
If level and peaking is available on the connected receivers, adjust it as follows:
1.
If using an oscilloscope, apply a white field test pattern to one the local (VGA) inputs
on the MTPX Plus (see figure 55).
If using a monitor, apply a Color Bars test pattern to one the local (VGA) inputs on the
MTPX Plus.
TIP: The Extron VTG 300 or VTG 400 are recommended to provide the test pattern.
2.
Tie the local input receiving the test pattern signal to the output connected to the MTP
receiver to be optimized.
